Ladies/Gentlemen:

     Reference is made to the Revolving Credit and Security Agreement between us
bearing an effective date of July 27, 2001 (the  "Agreement").  All  capitalized
terms not  otherwise  defined  herein shall have such meaning as are ascribed to
them under the Agreement.

     This letter shall serve to confirm that the Agreement  shall be temporarily
amended by  suspending,  until April 30,  2002,  the  requirements  set forth in
Section  12(s),  requiring  Borrower  to at all  time  maintain  Minimum  Excess
Borrowing   Availability  of  not  less  than  Five  Hundred   Thousand  Dollars
($500,000.00).  Effective  April 30, 2002, the provisions of Section 12(s) shall
be reinstated and enforced.  This of course should not in any way be regarded as
a waiver or suspension of any other provision of the Agreement  either temporary
or otherwise as it is our  expectation  that you will remain in compliance  with
all of the terms and provisions of the Agreement.

     This  letter  shall  also  serve to  confirm  that we will  extend to you a
temporary  discretionary  over-advance  facility of up to Five Hundred  Thousand
Dollars  ($500,000.00)  in excess of the Formula  Amount  until March 30,  2002.
Effective March 30, 2002, this  over-advance  facility shall terminate and it is
our expectation that all of your Loans shall be within the Formula Amount.

     Except as hereby  modified or amended all of the terms and provision of the
Agreement  shall continue to remain in full force and effect in accordance  with
their original terms.

     If the  foregoing  correctly  sets  forth the  agreement  between us please
execute a copy of this letter in the space provided below and return an executed
copy to our offices.

                                        Yours very truly,
                                        GMAC COMMERCIAL CREDIT LLC
